Today, the fundamental idea remains much the same - "the interaction of superimposed graphics, audio and other sense enhancements over a real-world environment that’s displayed in real-time".

In looking to better understand AR it is important not to confuse it with Virtual Reality (VR) - where the primary goal is to replace the real world with a simulated one.

In 2014, I was introduced to AR by ..... at the State of Play at Dublin Institute of Technology. Some moths later he approach us at AbydosGAMETECH to help insert 'surround sound' into their ......

More recently, AR came up in discussions with colleagues of mine, David Grainger of 'BeatStressSimply and Tom Keane of Retail Anywhere who are activley considering inserting AR into their respectice Apps. 

AR can refer to technologies which have existed for years.

Take for instance sports telecasting where you see colored lines drawn against real-time gameplay for say, a rugby or soccer match. These lines may be used to indicate the offside boundaries in which the players must not cross or to show the movements of the ball or players. AR is not to be (commonly) confused with Virtual Reality (VR), where the primary goal is to replace the real world with a simulated one.

We often take such existing technology for granted because they are so prevalent and commonplace that we don’t associate them with what we normally assume as ‘high-tech’ AR.
